Check the lpServiceStartName parameter of CreateService()[^]. Make sure this user has access to to required network resource.

Thanks a lot
But, Do You Mean That I Can LogOn To System via
CreateService() ? i.e I Can Determine the UserName
and Password In this Function !!!Or a service Can Act
As Users? It is Something new for ME,
Would you pls, Discuss A little about your Idea?

By default when you double click a exe it runs under the same user account by which you logged on the the system. But a service starts executing before a user login to the system. So you have to say to the system, under which user account the service should be run, this should be done while the service is created/registered to the system.
CreateService() is the API to Create/register the service with the system and
lpServiceStartName & lpPassword are parameters through you say to the system, under which user account the system should run your application as service.

Is LogonUser() what you are looking for?

In MFC applications you don't usually call EnableMenuItem() directly. Take a look at How to Update User-Interface Objects[^]

I don' t know if the problem was clear. I don't want to remove the ethernet-card. I will remove the cable from the Adapter. In this case windows shows a tip text message in the right bottom corner.
I thought that I can caught this windows message.

Add 1st project to the second projects solution. Now from the resource view -> Drag and drop the required *Dialog* between the projects. Remember to hold the "Ctrl" while dragging.

I assume you have a class connected to the dialog. I also assume that it is an MFC project. I also assume it is VC6.
Right-click on the dialog class. A menu appears. Click "Add to Gallery".
Then in the other project, go to Project->Add To Project->Components and Controls. Then open the folder for your old application in there. It should have a file called: xxxx.ogx.
Add it to your project. It adds the class, as well as the dialog resource.

this is this.

project dependancies in vc6.00

rrrado3-Jul-05 23:20

3-Jul-05 23:20

I have project wich is dependant on another project. I've set this in the Project>Dependancies. Project P2 is dependant on project P1. P1 contains Release and Debug configurations (builds P1.lib).
P2 contains Debug, release, Release 2 and release 3 configurations.
Where to specify that for example P2/release3 is dependant on P1/Release ?
For Release 2 this is working good, but for release 3 it's trying to build and link it with debug version of P1 althought I've used release 2 as original when I was creating release 3. I didn't change anything after creating release 3!

Any ideas ? Thank you !

MFC: Use same menu for mainframe and childframe

Wim Jans3-Jul-05 23:18

3-Jul-05 23:18

Hello,

I'm having a bit of a problem using the same menu for my mainframe and childframe.
Basically I don't need the menu that comes with the childframe.

In my mainframe menu, I'm dynamically building one menu entry, and I don't want to do this processing for every child window I open, that's why I want to use the mainframe menu for the childmenu.

Is there a way to prevent loading of the childframe menu?

I tried to load the mainframe menu in the OnCreate Handler of my childframe, but that doesn't seem to work:

<br />
int CChildFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) <br />
{<br />
	if (CMDIChildWnd::OnCreate(lpCreateStruct) == -1)<br />
		return -1;<br />
<br />
	CMDIFrameWnd* frame=(CMDIFrameWnd*)AfxGetMainWnd();<br />
	CMainFrame* mfrm;<br />
<br />
	mfrm=(CMainFrame*)frame;<br />
<br />
        CMenu NewMenu; <br />
	NewMenu.m_hMenu=mfrm->m_hMenuDefault;<br />
	ASSERT(NewMenu);<br />
	SetMenu(NULL);<br />
	::DestroyMenu(m_hMenuDefault); <br />
	SetMenu(&NewMenu);<br />
	m_hMenuDefault = NewMenu;<br />
<br />
	return 0;<br />
}<br />

Just do what I do - remove the second menu from the project entirely. When MFC tries to swap menus, it
fails, and gives up with a TRACE complaint. But my first menu is untouched. You just have to make sure
it has all the menu options you'll want on it, as you won't be swapping depending on situation.

developing software for windows server

3-Jul-05 22:55

Hi all,

Just wondering if anyone can point me in the general direction of some resoures relating to developing software for Windows Server 2000/2003. I'm developing a back-end processing application that I'd like to run on Windows Server. Basically, all it does is connect via ODBC to a database, do some statistical analysis, and then append a couple of tables. It needs to do be running constantly to be effective.

Obviously it's going to be a little different that the Windows front-ends I've been developing thus far. It's for the banking industry, so has to be fairly compliant with standards and fairly robust too. I guess running the app as a console app, or as a windows service, would be the way to go... anyone got any ideas?

Cheers,
Ritcho
